Old Bill and Son is a 1941 British black-and-white comedy war film directed by Ian Dalrymple. Centred on the First World War cartoon figure Old Bill and his escapades in the early Phoney War of World War II and with that character's creator Bruce Bairnsfather as one of its screenwriters, it stars Morland Graham, John Mills, Mary Clare and Ronald Shiner as Herbert 'Bert' Smith.
